To all whom t may concern Be it known'that I, Illimani O.' 'IHoMrson, a citizen of the United States, residlng` at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Railway-Car-Wall Constructions, of which the following is a specification.

My invention relates to railway cars and particularly to the wall construction offreight cars and has for its principal object to provide an improved end construction which may be easily and cheaply made and which is very strong and rigid.

A further object is to provide a simple construction whereby a metal panel section having transverse strengthening ribs may be secured to a corner post without the necessity for the special construction of thc corner post or panel section for this purpose.

The invention consists in the novel arrangements, constructions and combinations to be hereinafter described and claimed for carrying out the above stated object and such other objects as may appear from the following description.

The invention is illustrated in a preferred embodiment in the accompanying drawing, wherein; n

Fig. 1 is an end elevation of the superstructure of *a railway box car provided with an end wall construction in accordance with my invention. Y

Fi 2 is a vertical section taken along the line 2-2 of Fig. 1.

Fig. 3 is a fragmentary horizontal section taken along the line 3-3 of Fig. 1.

Like characters of reference designate like parts in the several figures of the drawm s.

*or the purpose of illustrating the application of my invention to a box car I have shown a conventional form of car having an end sill 10, side sills 11, floor 12, side wall 13, and roof 14. rI he end of the car' consists in the embodiment illustrated of a plurality of metal panels 15, 16 and 17 having smooth inner surfaces. The panels are ypreferably rolled and formed with solid strengthening ribs 18 on the outer surfaces. The number of sections forming the end wall maybe varied to suit the particular construction. For the' purpose of saving metal the panel sections are formed of different thicknesses, the thicker sections being placed in the lower part of the end wall in the region where the greatest strength is required. The adjacent horizontal edges of the sections overlap as shown at 19, the lower margin 20 of each of the two upper sections being offset as shown in order to provide a flat inner surface for the end wall.

As more clearly illustrated in Fig. 3, it will be-seen that the margins of the sections are secured on the outside of the flange 21 of the corner post 22. The corner post 22 is of angular cross-section as shown in Fig. 3. In the structure shown the corner posts require no special construction as in a structure in which the flanges are secured to the outer face of the panel and must conform. to the contour of the margins of the panel. No attaching flanges are necessary on the vertical margins of the wall panel and accordingly the panel section may be rolled or cut from stock.

The lower edge of the wall panel is secured to the end sill by means of the angle iron 23. The angle iron 24 serves to secure the upper edge of the wall panel to the plate 25 which in turn is bolted to the roof structure.l A lining 26 is preferably placed along the inner face of the Vend wall and may partially or entirely cover the end wall as desired. The vertical edge of the lining 26 is interposed between the end of the side wall 13 and the flange 21 of the corner post shown in Fig. 3.

l I claim:

1. In a railway car the combination with flanged corner posts of a wall panel comprising a rolled metal plate smooth on its inner surface and formed with solid transverse strengthening ribs on its outer face, said panel secured with its smooth face against the flanges of the said corner posts.

2. In a car, the combination with metal corner posts having inturned flanges, a wall panel comprising a rolled plate formed with solid outstanding integral ribs and a plain inner surface bearing against the inturned flanges of said corner posts.

3. In a railway car, the combination with the side wall sheathing of the car, angle iron corner posts having flanges to which said side sheathings are attached, and flanges inturned, a wall vpanel comprising a rolled plate formed with solid outstanding integral ribs, and a plain inner surface bearing against the inturned flanges of said corner posts, and a wooden lining the edges of which intervene between the side sheathing and the inturned flanges of the corner posts.

4l. In a railway car the combination with flanged corner posts oll a car Wall comprising a plurality of' rolled metal panel sections secured to said corner posts outside of the flanges, said panels overlapping and having the upper overlapping niargin offset outwardly to provide a plain inner surface for said car Wall.

5. In a railway car the combination with flanged corner posts of an end Wall comprising a plurality of rolled metal plates of different thickness having flat inner surfaces and strengthening ribs on the outer surfaces, said plates being overlapped with the thicker zontal margin offset at the overlappingjoints so as to form said end Wall with a flat inner surface.
